Are any VPN Modules required to configure site-to-site VPN on Cisco ISR Routers ? What are VPN modules for ?

I have this problem too.

Could you please also mention the difference between the performance on built-in encryption acceleration card and the AIM-VPN Modules for e.g. in case of 2821 routers.

Are the VPN modules visible from outside the router after installation or are they seated inside the router.
